四川遠教轉(zhuǎn)星調(diào)試說明書

1、四川省農(nóng)村中小學(xué)現(xiàn)代遠程教育項目衛(wèi)星數(shù)據(jù)接收系統(tǒng)轉(zhuǎn)星調(diào)試說明2007年8月關(guān)于遠教衛(wèi)星接收系統(tǒng)的轉(zhuǎn)星調(diào)試簡要說明本次衛(wèi)星接收的調(diào)整，是由于國家廣播電影電視總局將遠教項目所使用的電視節(jié)目以及IP數(shù)據(jù)資源，由原來的鑫諾1號衛(wèi)星轉(zhuǎn)播，調(diào)整為由亞太6號衛(wèi)星轉(zhuǎn)播。需要做的調(diào)試工作步驟如下：第1步：了解亞太6號衛(wèi)星的參數(shù)轉(zhuǎn)發(fā)器號：K4下行頻率（單位：MHz）：12395下行極化方式：垂直FEC：3/4符號率（Msps）：27.5第2步：調(diào)整衛(wèi)星接收機參數(shù)主要是通過接收機的遙控板或機身面板按鈕，進行參數(shù)修改，將原來的鑫諾1號衛(wèi)星的參數(shù)，修改成亞太6號衛(wèi)星的參數(shù)并保存（只修改衛(wèi)星參數(shù)）。修改完成后，即可使用它

2、來調(diào)整衛(wèi)星天線。天線調(diào)整到能鎖定衛(wèi)星后，使用自動搜索按鈕功能，搜索并保存電視節(jié)目。第3步：調(diào)整衛(wèi)星天線主要是調(diào)整天線的仰角（角度要減小一些，也就是天線現(xiàn)在向著天空要低頭一些），方位角（南偏東的角度要增大，也就是天線現(xiàn)在的方向會更偏東方一些）?？偟恼f來，站在天線后方，現(xiàn)在的天線方位要在原來的基礎(chǔ)上，向下低頭一些，并向左轉(zhuǎn)動一些。各地具體的仰角和方位角參見附表。參看下面的示意圖：天空地平現(xiàn)在仰角（亞太6號）地平原來仰角（鑫諾1號）天空天線天線天線仰角變化示意圖南東原來方位角（鑫諾1號）南東現(xiàn)在方位角（亞太6號）天線天線天線方位角變化示意圖先松動天線螺絲，然后慢慢搖動天線，最好先確定方位角，再慢慢調(diào)

3、整仰角，如此反復(fù)，直到出現(xiàn)信號質(zhì)量或信號電平。天線調(diào)整好以后，先固定，再連接好線纜。具體操作如下：調(diào)星時連接圖如下：通?？捎蓛扇艘黄鹋浜线M行調(diào)星：首先檢查天線與衛(wèi)星接收機相連接的線纜接頭（75-5頭）是否完好，再將接收機（需先將衛(wèi)星參數(shù)修改成亞太6號衛(wèi)星的參數(shù)）和一臺小電視機按照圖示連接好（最好衛(wèi)星接收機和電視挨著天線，以便及時調(diào)整天線），一人輕微、緩慢的上下左右搖動天線（注意動作幅度不要太大，并且要有耐心）；另一人監(jiān)控衛(wèi)星接收機上的信號質(zhì)量或中國教育臺電視節(jié)目（若無電視機則可直接監(jiān)控接收機前面板上的“鎖定”燈，或“LOCK”燈，燈綠表示信號已經(jīng)鎖定）。信號質(zhì)量或信號電平達到35%或以上（四川

4、地區(qū)通常會在60%以上），即可正常接收視頻及數(shù)據(jù)信號。調(diào)星完畢后，必須將天線的螺絲全部擰緊固定，防止風(fēng)力引起天線方向偏離。另外必須注意，禁止在通電的情況下插拔天線線纜，由于高頻頭需要接收機或接收卡通過75-5線纜饋電5V，所以帶電插拔時有可能會將高頻頭或接收設(shè)備燒毀。第4步：調(diào)整衛(wèi)星接收計算機參數(shù)打開計算機，點開衛(wèi)星接收卡的控制程序，將原來的鑫諾1號衛(wèi)星的參數(shù)，修改成亞太6號衛(wèi)星的參數(shù)并保存（只修改衛(wèi)星參數(shù)）?？刂瞥绦蜴i定衛(wèi)星后，即可打開IP數(shù)據(jù)接收軟件，進行IP數(shù)據(jù)資源的接收。注：四川各地的天線角度數(shù)，可以在文件后面所附參數(shù)表中查詢。附 四川衛(wèi)星接收設(shè)施調(diào)整參數(shù)表序號城市經(jīng)度緯度亞太6號（東
